    <subfield code="a">&lt;p&gt;Over 20 years ago Valenti &amp;amp; Piskuonov developed the stellar spectral synthesis library Spectroscopy Made Easy (SME) to simplify stellar spectral analysis, and it has been used in hundreds of works since.&lt;/p&gt;

&lt;p&gt;PySME is a new Python frontend to the same library, developed with the same goal in mind: Making spectroscopy easier for everyone.&lt;/p&gt;

&lt;p&gt;PySME creates accurate, high-resolution synthetic spectra, based on a range of stellar parameters, a linelist and a model atmosphere. It can also be used the other way around. Give PySME an observation and it will determine the best fit stellar parameters for that spectrum.&lt;/p&gt;

&lt;p&gt;This is also useful for Exoplanet research. It is important to understand the host star, to properly understand the workings of the orbiting planet.&lt;/p&gt;</subfield>
